Abstract

Highly efficient and environmentally friendly mechanical process was developed for the higher recovery rate and productivity in the recycling of waste jelly-filled communication cables. Only the simplest mechanical method was designed and built for a continuous process, further proved experimentally along with the addition of several parts such as brush-type rollers and scrappers. In this process, the recovery rate and productivity were 98% and 55 Kg/hr respectively. This process is thought to be simple but highly advanced method for the commercialization of green process.
